First of all, congratulations! [name_m]How[/name_m] tremendously exciting! I hope all is going smoothly. Now, I only picked my favorite names from your list to provide feedback on, so I hope that’s alright.
My favorites from your list…
[name_f]Marcella[/name_f] ([name_f]Marci[/name_f]) and [name_f]Penelope[/name_f] ([name_f]Poppy[/name_f]) - Both [name_f]Penelope[/name_f] and [name_f]Marcella[/name_f] are classic, timeless, and elegant names with rich history all their own. However, depending on which country you inhabit, popularity differences may be an issue for you, unless you don’t particularly care about that sort of thing. In the U.S., [name_f]Marcella[/name_f] is recognizable yet rare enough, but [name_f]Penelope[/name_f] is becoming more and more common. Again, I’m not sure if it’s anything to be concerned about, but I thought I’d mention it anyways.
[name_f]Nadine[/name_f] and [name_f]Naomi[/name_f] - Stunning choices. They’re both classy and cultured names, similar but different enough to not be too “matchy”, despite their shared initial. Hands down my favorite pair. You can’t possibly go wrong with either.
[name_f]Penelope[/name_f] ([name_f]Poppy[/name_f]) and [name_f]Clementine[/name_f] ([name_u]Clem[/name_u]) - I think I like this set a tiny bit more than [name_f]Penelope[/name_f] and [name_f]Marcella[/name_f], simply because [name_f]Penelope[/name_f] and [name_f]Clementine[/name_f] have similar vibes to me. [name_f]Poppy[/name_f] and [name_u]Clem[/name_u] would be darling names for sisters.
[name_f]Liesel[/name_f] and [name_f]Corrine[/name_f] - They strike me as ballerina names, for some reason. Dainty and sweet, but not too frilly.
In order…
[name_f]Nadine[/name_f] and [name_f]Naomi[/name_f]
[name_f]Penelope[/name_f] and [name_f]Clementine[/name_f]
[name_f]Marcella[/name_f] and [name_f]Penelope[/name_f]
[name_f]Liesel[/name_f] and [name_f]Corinne[/name_f]
I’m not sure if you wanted middle name suggestions or not, but I’d be happy to provide a few ideas if you’d like.
Good luck!
